WATE R-CRANE Application filed .Tune 19, 1908.

T o all 'whom it may concern:

Be it known that I, ROBERT A. OGLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tvlater-Cranes, of which the following is a specification.

My invention relates, more particularly, to improvements in water -eranes of the variety employed in railway equipments for supplying water to locomotive-tenders; and some of my objects are to render the valvemechanism of the crane easy of operation under high water pressure; to obviate any hammer eect of the water upon the parts of the valve when it is operated to close it; to produce slow turning of the valve in closing it; and to close the valve in such a inanner as to fully apprise the operator of the operation of the valve.

Other important objects of my invention are to render the connection of the spout section with the vertical pipe section of the crane capable of turning in any desired direction without turning the vertical column; to render this connection of such a character that under continuous use wear of it will not cause it to become leaky, but on the other hand will cause it, by such use, to produce a better joint; and to provide a construction 'by which the end of the spout, in movin@ from inoperative to operative position, will travel in a curved path, and when so moving will be raised to automatically clear any obstacle in its path, and be finally deflected into the inlet of the tank to be filled.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a broken view yin elevation and partly in sectional elevation of the upper end of a water-crane constructed in accordance with my invention. Fig. 2 is a view in sectional elevation of the lower end of the water-crane illustrated in Fig. 1. Fig. 3 is a view in front elevation and partly in sec tional elevation of the upper end of the water-crane illustrated in Fig. 1. Fig. 4 is a section taken at the line 4 on Fig. 3 and viewed in the direction of the arrow. Fig. 5 is a view in end elevation of the construction illustrated in Fig. 2. Fig. 6 is a section taken at the line 6 on Fig. 5 and viewed in the direction of the arrow. Fig. '7 is a section taken at the line 7 on Fig. 2 and viewed in the direction of the arrow and Fig. 8, a

section taken at the line 8 on Fig. 2 and viewed in the direction of the arrow.

The lower end-portion or water-box of the crane is represented at 9 and, as shown, is formed with an elbow 10 at the end 11 of which the water-main (not shown) through which water is supplied to the crane, may be attached, it being understood that this portion of the crane, as is commonly the practice, is located under ground. rlhe vertical pipe section 12 which extends upward about 14 feet above the level, is formed at its upper extremity with a tubular head 13, the upper open end of which is screw-threaded as indicated at 14 to receive a hollow bearing-head 15 of semi-spherical sha e as represented, the upper marginal eircu ar edge-portion of this head being provided with an inwardly extending annular flange 16 having a tapering upper' surface 17 forming a track, for a purpose hereinafter explained.

T ie spout which is represented at 1S is shown in part only, the portion shown being that which attaches to the vertical pipe 12. The portion of the spout illustrated is formed in sections to afford a head of general spherical shape, the upper section 19 of which being of semi-spherical shape, and its lower section 20, which is bolted to the upper section as indicated at 21, being likewise of general spherical shape, the inner surface of the section 20 being of a curvature corresponding with that of the outer surface of the head 15 about which this section 2O extends. The section 20 is provided with an annular flange 22 about its periphery, the under side of which flange describes an ogee curve as represented and forms a track 23.

The head 13 is so formed as to provide two sets of diametrically disposed horizontal lugs 24, in the construction illustrated these lugs being so positioned as to extend approximately parallel with the spout 18 when the latter is in inoperative position. These sets of lugs form bearings for vertically disposed rods 25 and 26 between washers 27 on which and the adjacent lower lugs, springs 2S are confined to normally hold the rods 25 and 26 in raised position. The rods 25 and 26 carry rollers 29 and 30, respectively, at their upper extremities, these rollers being so positioned as to cause them` to bear against the track 23, and the springs being so tensioned that the engagement of the rollers with the track will cause the section 2() to be lOO held. in close contact with the bearing surface of the head 15, regardless of the position of the spout, and thus constantly insure a tight joint between the spout and the head 15.

The head 19 carries two opposed hori- Zontal bosses 81 in which shafts 32 carrying rollers 33 on their inner ends are journaled, these rollers having beveled roller-surfaces, as indicated at 34, which roll upon the beveled track 17, as represented in Fig. 3, for a purpose hereinafter explained.

The track 23 is of such a curvature that the spout 18, when it is in the position relative to the rollers 29 and 30 illustrated in Fig. 1, and extends parallel with the track (not shown) along side of which it is stationed, inclines upwardly, in which position it is locked against accidental turning, as for instance when the wind is high, by engagernent of its roller 29 with a depression 35 formed in the track 23. ln this position of the spout the rollers 33 extend at right angles to the rollers 29 and 30, as clearly represented in lEig. 3. is the spout is swung about its connection with the head 13 to operative position at a right angle to the railway track, it is caused, hy the curvature of the track 23 to move in acurved path, the outer end or the spout gradually rising during the initial portion of its rnovernent hy reason of the rolling engagement of the roller 29 upon a cani-surance 36 of the track, and descending throughout the remainder of its move-nient as the roller 29 traverses an inclined surface 37 of the track, the curvature of this track lseing such that by the time the spout has nioved to a position in which it exe tends at a right angle to the railway track, the rollers 29 and 30 rest at portions the track, one of which is represented at 38, which are located in the saine horizontal plane. Thus when the spout is nioved into operative position, the rollers 33 extend iinrnediately above the rollers 29 and 30, and the spout, hy reason of its weight and the change of the fulcrurn point on account of these rollers moving from a position at rightangles to each other to position in which they Aare superposed, which results by so operating the spout, descends at its outer ends, in whicl'i lowered position it is intended that the water he supplied 'through the crane to the loconiotivetender` The description the valve-mechanism for controlling the ow of water through the crane is as follows: The elbovvr 10 at its junction with the vertical portion of the crane contains an annular inwardly extending flange 89 disposed at right angles to the wall of the elhow. A. hollow frusto-conical casing 40 having a closed end 41, an open end 42, and a circular wall 43, is secured to the flange 39 at a riin 44 on the casing 40, through the medium of bolts 45, the wall 43 ofthe casing, which is thus spaced throughout its extent from the wall of the elbow, containing equidistantly spaced ports 46. Rotatahly confined in the casing 40 to fit its tapering inner surface is a hollow plug 47, open at both ends and having ports 48 in its wall spaced apart from cach other in the saine manner as the ports 46 are separated. The interior of the plug contains two spaced transversely extending spider fraines 49 and 50, the frame 50 having a boss 51 containing an opening 52 through it concentric with the wall of the plug 47, in which opening a hollow shank 53 is keyed to render it niovable with the plug 47. The outer end of the shank 53, which is recessed as indicated at 54, is journaled in an opening 55 in the wall of the vertical pipe 12. A sleeve 56 is fixed on the shank 53, and extending from this sleeve is a crank-arm 57 to which a valve-operating rod 58 is secured, it being preferred that this rod be forrned in sections 59 and 60 adjustable with -relation to each other, as represented in Fig. 7. Thus by nioving the rod up and down, as hereinafter described, the plug 47 is caused to be turned in opposite directions in the casing 40 to cause the ports 48 in the plug to be inoved into and out of registration with ,the ports 46 in the wall 43 for controlling the flow of water through the crane.

ln the construction illustrated, the valveactuating rod 5S which extends upwardly through the center of the vertical pipe 12 is bifurcated at its upper end as indicated at 61, at a point approximating the center of the spherical heads 15 and 19, the rod 5S being provided near its upper end with a universal joint 62. Pivoted to the bifuroated upper end of the rod 5S, as indicated at 63, and extending rearwardly, is an arni 64 which is xed on a shaft 65 journaled in bearings 66 provided on the head 19, the ends of this shaft extending beyond the bearings 66 as indicated in Fig. 4. An operating lever 67 having a bifurcated portion affording arins 68 is attached at these arins to Athe outer ends of the shaft 65, as clearly illustrated in Fig. 4, this lever extending above the spout and substantially parallel with it. The lever 67 at its connections with the shaft 65 has a yoke-extension 69 which preferably extends approximately in the saine plane with the arin 64, and carries at a stein 7 O thereon an adjustable weight 71 tending norinally to turn the shaft 65 in its bearings to raise the levers 67 and 64 and rod 5S, the rotary plug 47 being so positioned with relation to the rod 58 as to cause the ports 48 in the plug to be out of registration with the ports 46 in the casing 40 when the lever 67 and rod 58 are in their nornial positions as represented in Fig. 1.

The operation of the apparatus as described is as follows: The normal inoperative position of the crane is that illustrated in Figs; 1, 2 and 3 in which the roller 80 engages with a low portion oi' the track 28 and the roller129 rests in the recessed portion 35 thereof, thereby causing the spout to incline upwardly, it being intended that the crane be so positioned along side oi a railway track that when v)its spout is positioned as just described it will extend parallel with the railway track and-be normally out of the way of passing trains. W hen the parts are so positioned it .willl be noted that the head 2O is held in engagement with the outer semispherical surface of the head 15 by the engagement of the spring-supported rollers 29 and 30 with the track 23, and that the spout 18 is prevented from tilting side wise by the engagement of the rollers 38 with the track 17. In this normal position of the apparatus, the lever 67 and rod 58 are raised and the ports 48 in the valve-plug 47 are out of registration with the ports 46 in the casing-wall 43, communication oi the passage in the elbow 10 with the passage in the remainder of the structure being closed. When it `s de- Isired to operate the crane to supply water to a locomotive tender, for example, on a railway track beside the crane, the operator grasps the spout and swings it from its normal position described to a position in which it extends at a right angle to the railway track. In so swinging the spout, it turns at its spherical bearing connection with the head 15, the tr ck 23 moving in contact with the rollers 29 and 30, causing the outer end of the spout 18 to move in a curved path, first rising by reason of the cani-surface 36 and then gradually descending as the inclined portion 37 of the track rides on the roller 29, the curvature of this track, as before described, being such as to permit the outer discharge end of the spout to descend into the inlet of the tender. In this position oi' the spout the`rollers 38 are above the rollers 29 and 30, and the spout 18 is thus free to drop by gravity to the downwardly inclined discharge position. `With the spout in operative position, the operator then pulls down the lever 67 thereby rocking the shaft 65 and lowering the rod 58 against the resistance of the weight 71. By lowering the rod 58, the plug 47 is turned in the casing 40 to cause its ports 48 to register `with the .ports 46 in the casing-wall 49, and

the water entering the elbow 10 from the water-main connected with it, Freely passes through the valve and vertical pipe section 12 and out at the discharge end of' the spout. It will be noted that the effect of the water pressure against the head 19 of the spout tends to lift the latter, thereby relieving the pressure of the head 19 on the springs 28 and y such lifting action tending to force the semi-spherical head 20 into closer bearing contactt with the correspondinglyshaped bearing-,surface of the head 15. The eii'ect of this action is to cause an absolutely watertight connection to be allor-ded, the tendency being to cause this connection to be rendered more and more perfect as the use ol" the apparatus continues. lVhen it is desired to arrest the liow of water through the crane, the operator releases the lever 67, whereupon the latter swings to normally raised position under the action of the weight 71 and draws the rod 58 upward, with the result of causing the ports 48 in the plug 47 to be moved out of registration with the ports 46 in the casingwall 43, thereby closing communication between the elbow 10 and the vertical pipe 12. To avoid too rapid ascending ol" the rod 58 and the consequent rapid turning of the plug 47 when the lever 67 is released as described, l provide a cushioning device, oi which the following is a description: The recessed end 54 of the shank 53 extends beyond the wall of the pipe 12 and has lixed on it a sleeve 72, this sleeve having a crankextension 7 3 connected to the piston 74 of a dash-pot 75 of ordinary construction, through the medium of a link 76. The dash-pot contains two openings 77 and 78 in its rear wall 79 communicating with the interior of the pipe 12, the opening 78 being controlled by a needle-valve 80. rihe walls of the dash-pot contain a third opening 81, this opening being located in its outer wall a slight distance above the opening 77. The piston 74 is of a size and the openings 77 and 81 are so located as to render communication between the interior of the pipe 12 and the opening 81 closed when the piston is in the raised position illustrated in Fig. 6, and to cause connnunication to be open between the opening 81 and the interior of the pipe 12 when the pistou is at thelimit of its downward stroke. The position occupied by the piston 74, when the rod 58 is down and water is discharging through the crane, is that illustrated in Fig. 6. Thus when the operator releases the lever 67 and the red 58 starts to move upward, as before described, its speed of movement is regulated by the speed of movement of' the piston 74 in forcing `he water from the dash-pot out ol" the opening 78, and the rod may thus be caused to turn the valve as slowly as desired to obviate uf'ater-hannner.

1 preferably so construct the rotary valve mechanism as to cause the plug 47 to be loved slightly in a longitudinal direction to eilect close engagement with the inner surface of the casing-wall 43, when the rod 58 is actuated to close this valve; and to withdraw it slightly when the rod is actuated to open the valve, this result being accomplished by the following-described construction: The outer end ol the shank 53, which is of circular sha )e in cross-section, carries a thread 82 which screws on to a threaded boss 88 on a plate 84 adjustably secured, as

by bolts 85, to the wall S6 of the pipe 12, in line withthe shank 523. The threads of this threaded connection of the shank 53 with the plate 84 are so disposed as to cause the shank to partially unscrew from the boss 83 when the rod 58 is moving downward as described, and thus the plug 47 is forced at its outer tapered surface into intimate contact with the inner surface of the casing-wall 43 and to cause the shank 53 to screw upon the boss 83 when the rod 58 is lowered, this feature of the construction insuring a tight valve joint and at the same time preventing the binding or sticking of the valve. As supplementary means for preventing any hammer blow of the water upon the parts of the construction when it is shut oil', i provide a valve, comprising a head 87 normally seating in an opening 88 in the closed end 4l of the casing 40, under the influence of a spring S9 surroimding the outer end of a valve-stem 90 carrying the head 87, and confined in the recess 54 in the shank 53, to bear against a washer 91 on the stem, and a plate 92 bearing against an adjusting screw 93 in the plate. The spring SQ is so tensioned that the pressure of the water as it flows from the elbow 10 to the pipe 12 will not unseat the valve 87, but will do so should the water be shut olf suddenly enough to produce a water hammer.

By providing the beforedescribedconnection between the spout 18 and the pipe 12, =the use of objectionable cup-leathers, or the like devices, are avoided, and the joint thus formed instead of being liable to impairment from use, becomes more perfect as the usefof the apparatus continues.

By constructing the rotary valve in accordance with my invention, it is rendered completely balanced, permitting it to be turned in either direction with great ease regardless of the water pressure employed.

Another important feature of my-invention is that of so constructing the lever mechanism as described as to permit the operator,

by observing the lever 67 after he has released it, to know whether or not the valveY controlling the flow of water through the crane is being turned to shut off the water, as in doing so in the described construction the lever 57 must rise. Thus the liability of successive operations of the lever mechanism by tne operator in order that he may be certain of the shutting off of the valve, and consequent flooding ofthe ground about the crane, is avoided.
